High temperature in the thrust bearing of the centrifugal compressor
Thread Content
After the centrifugal compressor was overhauled and restarted, the temperature of the secondary thrust bearing was higher than that of the primary thrust bearing: 70°C for the secondary bearing and 40°C for the primary bearing. What went wrong?
There may be a shortage of oil; it is recommended to resolve this issue before continuing operation. The normal temperature for bearings is around 40 degrees.
It’s already running; there are no major issues, so it can’t be stopped
It is recommended to start from the installation perspective.
The lubricating oil does not provide sufficient cooling, or the main clearance is too large. If it can’t be stopped, it’s recommended to check the lubrication oil pressure
Subsequent changes in shaft displacement are caused by an increase in bearing load. Personal opinions are for reference only
The main drive temperature is normal, and the lubricating oil pressure is not low
